To all whom it may concern:

Be it known that I, JOHN SGHEMINGER,

Jr., a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented 'certain new and. useful Improvements in n rotary oil burners of the type shown in my Patent No. 1,442,786, dated January 16, 1923, and more particularly to anoil dis tributing head of improved construction.

The objects of-the invention are to provide a simple, inexpensive and durable device for atomizing oil or other liquid fuel and mixing the same with air-in suitable proportions to support combustion with greater eificiency and economy in the use of liquid fuel than is possible in using devices of this character as heretofore constructed. The invention will first be hereinafter more particularly described, with reference to the accompanying drawings illustrating a preferred form of embodiment of my invention, and then pointed out in the claims at the end of the description. In said drawlngs,

Fig. 1 is a vertical sectional elevation of an oil distributing head embodying my invention; parts of the burner and its supporting base or standard being broken away;

Fig. 2 is a horizontal sectional plan view taken on the line 2-2 of Fig. 1, looking in the direction of the arrow; and

Fi 3 is a detail sectional view taken on the hue 3- 3 of Fig. 1.

Referring to said drawings, in which the same reference letters are used to denote corresponding parts in different views, the letten A denotes a hollow. supporting base or' standard, within which'a vertical tubular shaft B has its bearingsJ An oil feed pipe.

'- C extends up through the shaft B and onthe shaped hub portion E of the head. 'Below the distributing head there is v projecting end thereof is secured a spreader D of inverted bowl-shaped form, over the surface of which oil issuing from the feedv pipe is spread and delivered into a cupdistributing a circular plate F having a central opening through which the shaft B extends and orn-ms'rnmorrne HEAD.

or flange g .to effect a sealed joint connec- I tion with the fire clay or other material at the bottom of the fire-box or around the inner wall of the combustion chamber within which the distributing head may be placed, as shown, for example, in Fig. 2 of the drawings of my aforesaid patent. Said plate G serves as a drip pan. and is mounted upon and secured to the hollow supporting base or standard A by means of tubular posts H and bolts passing therethrough and throughalined holes in the plate and an an nular flange or inner circumferential part of the plate; said bolts having threaded ends and nuts screwed thereon for securing the parts together. Within the lower plate or drip pan F, between it and a coverlate I, is placed an annular distributing p ate K, having a central opening through which the shaft B passes and having its inner edge around said opening upturned to prevent the fuel oil from escaping downwardly .through said opening. .The distributing plate, K is secured to the under side of a superposed plate L, by means of hangers or brackets depending from the plate L and secured thereto and'to the plateK by suitin the flanged ends of the hangers, or by spot-welding or other suitable means. The cover late, which is of dish-shaped form, inverte is supported upon the upper edge or marginal flange of the hub portion E of the distributing head, and has secured on the under side thereof the upper edges of a series of vertically disposed fan blades M, which are preferably dis osed at an angle to the radius of the plaih, and the intermediate plate L is secured to the lower 'edges of,said series of'fan blades, preferably by means of apertured flan es on the upper and lower edges of said an blades and bolts passing through the apertures in said flanges and through registering a ertures in the upper and lower'plates. aid intermediate plate L is preferably arranged a greater distance below the cover plate V f; than i-ne I i is M trioutini; ola e from the periphery of the oil distributing plate, between it and the periphery of the cover plate, thus enabling the airto catch up the oil and effect a thorough commingling of the oil therewith as it is discharged into the tire-box. The cover plate has a central opening therein around which there is an upturned marginal portion or flange over which is fitted a removable cap z'. The bot tom of the hub portion is formed or pro vided with a series of holes in which are fitted pipe sections or tubes 6, the lower ends of which project into the space between the bottom plate and the intermediate plate, for discharging fuel oil onto said bottom plate around. the central opening therein to be spread over the surface thereof by centrifugal force. it may be desirable, in some cases, to providewithin the hub portion of the distributing head, adjacent to its outer vertical wall, pocket-like projections 6 adapted to gather oil thrown out by centrifugal force and direct the same into the tubes 2.

It will be seen that the central plate of the distributing head is of less diameter than both the cover plate and the oil distributing plate, in order that the latter plates may closely approach each other at their outer edges and thus form a restricted annular space adapted to increasethe discharge velocity of both air and oil.

Another important feature resides in loeating the oil distributingplate at the bottom of the distributing head, thus interposing between it and the firebox both the cover plate and the central or intermediate plate.

In operation, fuel oil entering by the feed pipe is spread over the concave surface of the bowl-shaped spreader and-evenly distributed upon and around the bottom of the cup-like hub portion E from which the oil passes through the tubes onto the concave surface of the distributing plate K surrounding the central opening therein, and as said distributing plate is rotated the oil is spread evenly and uniformly over the sur-,,

face thereof and discharged at its periphery through the restricted opening between the peripheral portion thereof and the periphery of the intermediate plate and the overlying periphery of the cover plate, at which point air, entering from below the drip pan and drawn upwardly along the central space around the vertical shaft and between the m new,

fan blades is caused to pass outthroughsaid restricted opening and thus eflect a thorough commingling of the air and gas, and this idly moving body of air is interposed be tween the cover-plate and the distributing plate, sot-hat the oil on the surface of the,

latter plate is kept at a moderate temperature until it is forcibly discharged into the fire-box commingled with the current of air issuing through the same restricted outlet.

\ Having thus described my invention, what I claim as new and desire to secure by Let ters Patent of the United States is:

In a rotary oil burner, a distributing head comprising an annular distributing plate having a central opening therein and a superposed cupshaped hub portion carried by a vertical tubular shaft, a cover plate of substantially dish-shaped form inverted supported on said hub portion, an annular plate supported between the first named plates having a central opening therein and terminating short of the peripheriesof said top and bottom plates; the peripheral'portions of said top and bottom-plates terminating in close proximity to the periphery-of said intermediate plate; said shaft extending up through the central openings in said intermediate and bottom plates, and said cover plates having secured on the under side thereof a series of fan blades to the lower edges of which said intermediate plate is secured, and said bottom plate being connected with and-carried by said intermediate plate.
